碩士 === 國立臺北科技大學 === 電機工程系 === 107 === In recent years, Taiwan's power policy has targeted non-nuclear homes and renewable energy grid. Develop wind and solar power to reduce environmental damage and safety considerations. Power scheduling issues in power systems are another important goal. How to minimize the total power generation cost of the unit and the power loss of the transmission line, and achieve power supply stability by the reactive power compensation device and controlable load bus voltage. This thesis uses economic dispatch and power flow theory, and the imperialist competition algorithm to achieve the best scheduling of active and reactive power. The power-scheduling problem is divided into three cases: active power scheduling, active-reactive power interactive scheduling and active-reactive power combining scheduling. After analysis, the active-reactive power consolidation scheduling can effectively reduce unit costs. In this paper, simulate with IEEE 30-bus system, the imperialist competition algorithm is applied to optimize the scheduling. According to the simulation results, the total cost of power generation can be reduced, and the bus voltage is in a reasonable range, which proves that the method is feasible. Hope to provide a more economical reference for dispatchers.
